DEVICE FOR INTRODUCING PANS INTO MUFFLE-FURNACES.

SPECIFICATION forming part of Letters Patent No. 240,965, dated May 3,1881.

Application filed February 4, 1881. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE P. CHAPMAN, of Waterbury, in the county ofNew Haven and State of Connecticut, have invented a new Im- 5provementinDevicesforIntroducingPansinto Muffle-Furnaces; and I dohereby declare the following, when taken in connection with theaccompanying drawing and the letters of relerence marked thereon, to beat'ull, clear, and

I exact description of the same, and which said drawing constitutes partof this specification, and represents a perspective view.

This invention relates to a device for introducing loaded pans intomuffle-furnaces. The

1 heat at the mouth of the muffle, when open, is so great that theworkman cannot approach so near as to directly introduce the pans. Theusual method of doing this work has been to employ a number of men withlong poles or rods, which they placed against the pan and pushed itforward into the muftle. The opera' tion requires considerable power,because the pans, when charged, are very heavy.

The object of this invention is to avoid the 2 employment of so many menand make the introduction easier; and the invention consists in theconstruction as hereinafter described, and particularly recited in theclaims.

A is the mouth of the muffle, the door B 0 represented as raised bymeans of the usual lever C attached thereto.

Extending from the mouth and flush with the floor is a pair of skids orsupport, D, on which the pan E is placed. The door of the muffle beingclosed, the metal or articles to be introduced to the muffle are placedon the pans, as shown in the drawing. After the pan has been thuscharged the workman takes in hand the rod F, applies the forked end ffto 0 the pan, the rod being of the usual length, so that the workman maystand at some distance which the chain may be Wound.

from the furnace-mouth. The rod is here represented as resting in asupport, G; but such a support is not required, the operator being ableto hold the rod.

Attached to the rod F is a chain or cord, a, extending toward themuffle. It passes over a fixed pulley, H, and returns back from themuffle to a Windlass or other mechanism, upon The door is raised and thepower applied to draw upon the chain. The pan is forced forward into themuffle, guided by the workman through the rod F. The rod may then bedisengaged, and the door closed in the usual manner.

The rods, as usually considered, are made with a singlepoint ofconnection with the pans. By employing a bifurcated or forked end on therod a double connection is made and the guiding more readily performed.

It will be understood that the pans must be moved into the furnace to aconsiderable distance, which is the reason for attaching the chain sofar back upon the rod. By this arrangement a single man will introducethe pans 6'5 with greater facility than several men by the usual method.

I claim- 1. The combination of the support for the pan flush with thefloor of the furnace, the fixed 7o pulley H, and guiding-rod F, and thechain or cord attached to the rod at a distance from the pan,substantially as described.

2. The combination of the support for the pan flush with the floor ofthe furnace, the 75 fixed pulley H, and guiding-rod F, bifurcated toform two points of connection with the pan, substantially as described.
